Description

Description: TECHNICAL FIELD The present invention relates to a deep water pumping apparatus. More specifically, the present invention relates to a new deep water pumping device capable of efficiently pumping deep water rich in nutrients to an upper water area and contributing to the formation of a new fishing ground and marine environmental conservation. .

(Conventional technology and its problems) Conventionally, means for utilizing eutrophic substances in deep sea waters of the ocean have been studied, and this deep water is pumped up by pumps already installed on the Gulf coast, and this is used as a new fishing ground. The study to use it as a nutritional resource for food is also being specifically promoted.

As another means of pumping, it has been proposed to use a seawater flow in deeper deep waters and to install a barrier on the seabed to change this flow into an upward flow.

However, from the viewpoint of the formation of new fishing grounds by using deep water, the preservation of the marine environment, and the purification of the marine environment, although these conventional examination means can be found to be of some significance to concrete trials, in practice, these proposals have already been proposed. There was a major problem with these measures.

In other words, although the deep water pumping method can be realized by relatively small-scale equipment, the pump power for pumping deep water by pipes is greatly restricted, and its capacity and required power There were difficulties in achieving a practical scale in energy and the like.

On the other hand, in the case of the method of generating updraft by construction of a barrier, etc., the installation area is naturally limited because it depends on the direction of seawater flow, its speed, the seafloor topography, etc. It is not easy to install barriers because the construction itself becomes large and affects the flow of seawater and the navigation of ships.

In addition, the shape and size of the barrier for forming the updraft is still unknown as to its effectiveness as a practical scale.

Therefore, the present invention has been made in view of the circumstances described above, and pays attention to the advantage of the pumping method that can be realized even on a smaller scale, and saves energy for pumping power, at low cost, Moreover, it is an object of the present invention to provide a new apparatus capable of pumping deep water on a practical scale.

(Means for Solving the Problems) The present invention solves the problems as described above, and includes an overtopping wave generating section having an inclined surface for converging and rising a water surface wave and a gradually reducing side surface portion, and an inclined surface top portion. A drop line that collects and drops overtopping waves, a wave-overlapping pipe provided in this dropping line, and a connecting portion that has a narrow gap at the top of the wave-overlapping pipe, and the lower end opening faces the seabed. And a drooping pipe which is suspended at the upper part of the drooping pipe as the surface wave focused at the overtopping wave generator falls down the pipeline as an overtopping wave and is released from the overtopping wave discharging pipe into the sea. Provided is a deep water pumping device characterized in that deep water is pumped from a lower end opening of a drooping pipe due to a pressure drop in a narrow gap portion, and the deep water is discharged from an overtopping discharge pipe.

In addition, the present invention provides an overtopping wave generating section having an inclined surface for converging and rising a water surface wave and a side portion of gradually decreasing size, a falling conduit for collecting and dropping overtopping waves exceeding the top of the inclined surface, and a falling conduit for the falling conduit. A wave overtopping discharge pipe provided, and a drooping pipe having a discharge port at the upper end and a lower end opening facing down to the sea floor and hanging down from the falling pipe, and coaxial with the falling pipe and the hanging pipe A rotating screw is provided to rotate the screw of the fall pipe at the time of dropping and discharging of overtopping waves and simultaneously rotate the screw of the drooping pipe, thereby drawing deep water by suction and discharging it from the discharge port at the upper end of the drooping pipe. A characteristic deep water pumping device is also provided.

Hereinafter, the deep water pumping apparatus of the present invention will be described with reference to the attached drawings.

FIG. 1 shows an example of the apparatus of the present invention. For example, as exemplified in FIG. 1, in the apparatus of the present invention, an inclined surface (1) for converging and rising water waves and side portions (2) of gradually decreasing width on both sides of the inclined surface (1). And a pipe (4) for collecting and dropping overtopping waves over the top of the inclined surface (1), and discharging the overtopping waves to the oligotrophic water layer near the water surface. Discharge tube (5).

Further, a drooping pipe (6) for pumping nutrient-rich water in the deep water body layer is provided at a lower portion of the falling pipe, and a connecting portion of the drooping pipe (6) with the discharge pipe (5) is narrow. A gap (7) is formed, and deep water is suctioned and pumped upward through the drooping pipe (6) as the pressure generated by the release of the overtopping wave that is dropped and released here is reduced.

The deep water sucked and pumped is discharged from the discharge pipe (5) together with the overtopping wave toward the oligotrophic water layer.

A plurality of inclined surfaces (1) and side surfaces (2) of the overtopping wave generator (3) are provided, for example, as shown in FIG. Fall energy can be generated in the conduit (4). The energy to be generated can also be controlled by the height and size of the overtopping wave generator (3) and the height and size of the falling pipe (4).

In this way, by utilizing the waves on the ocean surface as overtopping waves, deep water can be automatically pumped up and eutrophic deep water can be supplied to the oligotrophic water layer near the water surface.

This pumping device is also fixed to the seabed by an anchor (9) via a wire (8).

FIG. 2 shows another example of the present invention. In this example, screws (10) and (11) that rotate coaxially are provided in the drop conduit (4) and the drooping tube (6), and the screw (10) is rotated by the falling overtopping wave. The upper pumping screw (11) is rotated.

Further, in this example, the dropped overtopping wave and the deep water sucked and pumped by the screw (11) are respectively discharged from separate discharge pipes (12) and (13).

For example, the device of the present invention having the above configuration achieves the following excellent effects.

Of course, it goes without saying that various aspects of the details of the device configuration are possible.

(Effect of the Invention) <1> It can be installed in any sea area suitable for artificial fishing grounds.

<2> It is possible to freely determine the discharge position of deep water so that the plankton breeding system is most efficient.

<3> Since the water pressure, the load, and the like do not act, there is almost no need to consider the strength of the structure itself, and the weight can be considerably reduced.

<4> Because deep water can be supplied stably,
Enables development of stable plankton propagation system and its evaluation prediction.

<5> Applicable to deep sea areas with a depth of 200 to 300m.

<6> It is not necessary to pay attention to the stable stratification effect due to the density of the ocean.
